This study was designed with the purpose of testing the psychometric properties of the Spanish version of the Attitudes toward Prostitution and Prostitutes Scale through three studies with different samples. The first one explores the test's dimensional structure or constructs validity through confirmatory factor analysis, as well as internal consistency and test-retest reliability. The second one focuses on discriminant and criteria validity. Finally, the third one examines the scale's convergent validity and its sensitivity to detecting changes. The results support two subscales with an optimal index of internal consistency, structural stability over time, and discriminative power between groups of participants. It is, therefore, an adequate tool for adults as well as young people and teenagers, and for detecting changes in the context of intervention or awareness workshops.

APPS-S：衡量西班牙人口对卖淫和卖淫妇女态度的工具

本研究的目的是通过对不同样本的三项研究来测试西班牙版对卖淫和妓女态度量表的心理测量特性。第一个通过验证性因素分析探索测试的维度结构或构造有效性，以及内部一致性和重测信度。第二个重点是判别有效性和标准有效性。最后，第三个检验量表的收敛效度及其检测变化的敏感性。结果支持两个子量表，具有内部一致性、随时间变化的结构稳定性和参与者组之间的区分能力的最佳指数。因此，它对于成年人以及年轻人和青少年来说是一个足够的工具，可以用来检测干预或意识研讨会背景下的变化。
